You are just rejecting reality then. You’ve said YouTube or other big social media to be the ‘virtual town squares’ but they are not, they are virtual malls. Also real life town squares can have rules imposed by the town council too.
They have plenty of other places to go with their content, some platforms aren’t for them and that’s ok. But they don’t want to express themselves shouting from a soapbox in the town square, they want to sell their content in the mall and these particular malls just don’t sell that kind of product.
Yep, it’s what the yanks call a townhall.
